Description
AI
The BH2227FV and BH2228FV ICs are 8bit R-2R-type D / A converters with 4 and 6 channels, respectively. Optimized circuitry allows two output voltages to be supplied (3V / 5V). Furthermore, the built-in RESET function ensures that the output voltage at all channels is Low during power up. A broad power supply voltage range is available (2.7V to 5.5V), providing design flexibility.
